HINGE.

Specification of Letters Patent.

Patented Mar. 16, 1915.

Application filed January 16, 1914. Serial No. 812,391.

To all whom it may concern:

Be it known that we, HARRY S. GETTY and JOHN EIOHEL, citizens of the United States, and residents of Philadelphia, county of Philadelphia, and State of Pennsylvania, have jointly invented certain new and useful Improvements in Hinges, of which the following is a specification, and which are illustrated in the accompanying drawings, forming a part thereof.

The invention relates to door hinges of the butt type, such hinges comprising a pair of leaves with alined pin sockets and a pintle for securing the two leaves together and constituting the pivot.

More specifically the invention relates to a hinge of this type in which the pintle is removable.

The object of the invention is to provide means for locking the pintle within the leaf sockets in such manner that it can be removed only when the leaves are in a given angular relation.

Hinges of this type are applied to a door by attaching the leaves, respectively, to the meeting faces of the jamb and the stile of the door. The joint of the hinge, therefore, projects beyond the face of the door, and if the pin is removable when the door is closed it becomes possible to open the door by withdrawing the pins, and the door may be replaced and the hinge pins restored to their position, leaving no trace of the means by which unauthorized access is secured to the room.

One form of embodiment of the invention is illustrated in the accompanying drawings, in which Figure 1 is a detail elevation of a door and casing to which the improved hinge is applied, the hinge being shown in longitudinal section through its joint; Fig. 2 is a detail section on the line 22 of Fig. 1; Fig. 8 is a detail section on the same line, the parts being shown in different positions; Fig. 1 is a similar section on the line 4. 1 of Fig. 1; and Fig. 5 is a detail of the hinge pintle.

The door jamb is represented at 10, and a door at 11. The hinge comprises the two leaves 12, 13, the former being adapted to be attached to the jamb and the latter to the door in the usual manner. Each hinge section is provided with a plurality of knuckles or sockets, those of section 12 being designated by the numerals 14, 15, and those of section 13 being designated by the numerals 16, 17 18. These knuckles are arranged in alinement, and their number will depend entirely upon the size of the hinge or the judgment or preference of the manufacturer. The pintle l9 enters the alined knuckles, securing the two leaves together and constituting the pivot upon which the door swings. As shown this pintle is provided with a knob or ball 20 at its upper end, serving the double purpose of a stop to longitudinally position the pin and as a means for withdrawing it from the hinge.

The pintle 19 is provided with a circumferential channel 21, which may, as shown, completely encircle it, and with a longitudinal passage or channel 22 leading therefrom to the inner end of the pintle. The longitudinal passage may comprise a mere flattening of the side of the pintle, as shown, and this form of construction is preferable for economy in manufacture. A pin 23 sets laterally through one of the knuckles, as 18, of the stationary leaf 12 of the hinge, and is so positioned that when the pintle is in proper place it will be in line with the annular channel 21 and will not interfere with the insertion and withdrawal of the pintle when the passage 22 is alined with it.

The pintle is fixed against rotation relatively to the movable leaf 12 of the hinge by any suitable means, as by a pin 24: fixed in the shaft of the pintle and entering a longitudinal channel 25 in one of the knuckles, as 16, of the hinge leaf. The pin 24 is so positioned relatively to the passage 22 that the latter is brought into alinement or register with the pin 23 only when the two leaves of the hinge arev swung apart, as by the opening of the door. A convenient arrangement of the parts brings them into this release position when the movable leaf has been swung through ninety degrees, as shown.

By the construction illustrated and described, the pintle is securely locked against withdrawal when the door is closed, but may be readily withdrawn when the door is open.

Various modifications of the invention are possible, and We do not, therefore, desire to be limited to the specific embodiment of it, Whl ChiWG havedisclosedf V w i We claim as our invention 1. In a hinge, in combination, a pair of leaves having alined knuckles, a pintle fitting Within the knuckles and havinga cir- I cumferential channel and a passage leading from the circumferential 'channel to an end of the pintle, a stud fixed in a knuckle of one of the leaves for entering such channel and passage, and means for preventing the rotation of the pintle With reference to the other hinge leaf.

2. In a hinge, lncomb'ination, a pair of leaves having alined knuckles, a pintle fittingwithin the knuckles and having a circumferential channel and a passage lead ing from the circumferential channel to an Copies 01' this patent may be 'obtained for five cents each, lay-addressing the cdmmissionet'otl atents,

"ea of the pintle, a as fixedin mane of one of the leavesfor entering suchvchannels, an d a stud fixed in the pintle-and engaging a longitudinal channel in of the other hinge leaf.

8. In a pin hinge, in combination, a leaf having 'aknuckle, a pintle fittingwithin the a knuckle knuckle, one of suchelements having a stud and the. other having a longitudinally disposed passage and a circumferentially dis posed channel for receiving the stud and means for preventing th'e 'pintle from being turnedwith reference to 'one' leafof. the

hinge.
